Differential Service & Repair in Phoenix
Your differentials let your wheels turn at different speeds through every corner. On trucks, SUVs and all-wheel drive cars, they work hard and need fresh fluid on schedule. We service them and repair them when they start to whine or clunk.
Signs of differential trouble
- A whine or howl that changes with speed
- Clunking when you start, stop or turn

- Gear oil leaks around the axle or differential cover

Frequently asked questions
How often should differential fluid be changed?
Follow your owner's manual. Towing, off-road driving and Phoenix heat can count as severe conditions and call for shorter intervals.
What does a bad differential sound like?
Usually a whine or howl that gets louder with speed, or a clunk when you start, stop or turn.
Do all-wheel drive cars have differentials?
Yes. AWD and 4WD vehicles have front and rear differentials, and many have a transfer case too.
Can you fix a leaking differential?
Yes. We replace the leaking seal or gasket, refill with the correct gear oil and check for damage.
